Possible Causes

Faulty BREW button on keypad, Loose keypad ribbon cable, Control board input failure, Safety interlock (lid or carafe) not engaged

How to Fix / Troubleshooting

Safety first: Unplug before opening the housing.

Check simple causes:

  • Ensure the carafe is fully seated on the warming plate.
  • Confirm the lid is fully closed and the brew basket is inserted correctly.
  • Try pressing the BREW button firmly for 1–2 seconds.

Inspect keypad connection (advanced):

  • Remove the top or front panel to access the keypad ribbon cable where it plugs into the control board.
  • Reseat the cable and ensure no corrosion or moisture is present.

If the display responds to other buttons but not BREW, the keypad membrane may be worn and require replacement of the control panel assembly.
